Patent TW-434999-B (TW)
Title: Engine operated generator
Inventor: SHIMIZU MOTOHIRO
IPC: H02P9/04
Filed: 1999-04-07
Granted: 2001-05-16
Abstract: An engine operated generator is arranged to constantly respond to a change in the load with a margin of power. The output current of the generator 1 driven by an engine 2 is rectified by a converter 3 composed of a thyristor bridge structure. A direct current released from the converter 3 is converted by an inverter 4 to an alternate current at a commercial frequency and connected to a load 5. A thyristor driver circuit 9 controls the conduction of thyristors so that the voltage at the input of the inverter 4 is constant. A fuel flow controller 10 detects the conduction angle of the thyristors and the revolution of the engine 2 is controlled so that the conduction angle is converged on a target conduction angle. Since the target conduction angle is set within a predetermined range smaller than the maximum conduction angle, the generator is maintained with margins of its output and can thus provide a stable level of voltage and respond quickly to a change in the load.

Title: Methods for embedding image, audio and video watermarks in digital data
Inventor: HO ANTHONY TUNG SHUEN
IPC: G06F21/60
Filed: 1999-09-14
Granted: 2001-12-11
Abstract: A method for embedding an entire image, audio or video watermark sequence within another image, audio or video data sequence with minimum loss of data quality is presented. The method exploits the de-correlation property of data coefficients in the orthogonal transform domain, similar to the application in data compression through transform coding. The present invention describes the usage of a discrete cosine transform as the embedding domain. However, other orthogonal transforms such as Fourier, Walsh-Hadamard, Haar, Sine and Wavelet can also be used for this operation. A unique key derived adaptively from spatial locations registering the thresholds of the ac transform energies is used to unlock or de-watermark the embedded image or audio sequence. Moreover, an exponential filter has been developed to compress and expand the watermark coefficients prior to the embedding and retrieval process. The method can be used in resolving multimedia copyright protection issues arising on the Internet and in the music industry, such as the inclusion of a company's logo or an artist's recorded voice. The method can also be incorporated as a built-in feature for digital recording devices, such as still and video cameras, as well as more recent devices such as VCD and DVD players. Moreover, the method can be applied to the commercial and service sectors, where security in transmission and reception of private information in terms of speech or image is of the utmost importance.

Granted: 2002-08-01
Abstract: An integrated process for treating pyrolysis gasolines by depentanizing the pyrolysis gasoline in a first distillation column reactor which also subjects the C5 fraction to selective hydrogenation of acetylenes and diolefins. The bottoms or C6+ material is then subjected to further distillation in a second distillation column reactor to remove either a C6 and lighter or C8 and lighter overheads which contains a benzene/toluene/xylene (BTX) concentrate while at the same time removing mercaptans and selectively hydrogenating the diolefins. The BTX concentrate is then subjected to hydrodesulfurization prior to aromatics extraction and separation of the benzene from the toluene and xylene. Concurrently with the benzene separation any remaining olefins are saturated to remove the color bodies. Finally the heavy gasoline fraction is subjected to the concurrent catalytic removal of mercaptans and separation to remove the heaviest material.

Abstract: A high energy photon source. A pair of plasma pinch electrodes are located in a vacuum chamber. The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line. A pulse power source provides electrical pulses at voltages high enough to create electrical discharges between the electrodes to produce very high temperature, high density plasma pinches in the working gas providing radiation at the spectral line of the active gas. A blast shield positioned just beyond the location of the high density pinch provides a physical barrier which confines the pinch limiting its axial elongation. A small port is provided in the blast shield that permits the radiation but not the plasma to pass through the shield. In a preferred embodiment a surface of the shield facing the plasma is dome-shaped.

Abstract: The present invention discloses a single-side sensing amplifier which comprises an output circuit with an output to indicate the status of a bitline node; further, providing a variable logic threshold inverter and an n-channel transistor for coupling or separating one of the input end of the output circuit with the bitline node. The variable logic threshold inverter has a larger and a smaller logic threshold voltages in which the larger logic threshold voltage is corresponding to a lower voltage level of a precharge signal and the smaller logic threshold voltage is corresponding to a higher voltage level of the precharge signal. The difference between the two logic threshold voltages represents a possible noise margin. Furthermore, a power down control circuit is coupled with the bitline node for reducing the static power consumption of the single-side sensing amplifier. The single-side sensing amplifier in accordance with the present invention provides a higher and adjustable noise margin which occupies smaller area on the semiconductor wafer.

Title: Color conversion device and color conversion method
Inventor: SUGIURA HIROAKI
IPC: H04N1/60
Filed: 2000-10-07
Granted: 2003-12-21
Abstract: Responsive to image data of three colors, six hue data are obtained, and then first comparison-result data each relating to one of the six hues, and second comparison-result data each relating to one of the six inter-hue areas are obtained. Matrix calculation is performed on the first comparison-result data, and the second comparison-result data, using coefficients. By varying the coefficients, adjustment can be made to only the target hue or inter-hue area, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be varied independently, and the large-capacity memory is not required. In addition, gray scale conversion is applied to the result of the matrix calculation, so as to compensate for the non-linearity of the output device.
